IMPROVEMENT iN HAND-STAMPS...

The Schedule refer-recite in these Letters Patentand making part of 'the same.

I, DANIEL NV. FISH, of Brooklyn, in the county of Kings and State of New York, have invented certain Improvements in Hand and Office-Stamps, of which My invention relates to a novel construction and arrangement of parts in that class of hand-stamps having a reveisihle die-plate and a tubular ink-fountain.

vFigure 1 is a front elevation of iny invention.v

Figure 2 i s a sectional lside elevation.

-Figure 3 is a vertical section of the die-plate and inking device.

Figures 4,5, 6, and 7, are details.

'lhe die-plateA is ,pivotedat the ends to the yoke Y B, to which the knob or handlev C is'attacli'ed. v

The die-plate is guided in its movement by slots in the bars a, and it is given a semi-revolution as it descends by means of the gear teeth b, which ineshf into corresponding teeth, c,4 upon one ot the guides c. It will he observed that a downward movement of the handle C causes the die to leave the ink-padagainst which it rests inverted, and become reversed in its descent by means ofthe gear-teeth, ready to inakef the impression upon the platen d below.

The guides c are suspended fi'oin the supporting;-

iieck D, formed upon or secured to the base E, and their lower extremities are suiiiciently above the surface of the platen d, to permit the introduction of the article to be stamped.

i By means of this arrangement of the parts, l ani l'enabled to use the reversible.die-plate and iiik-su pply fountain in' connection ,with the fixed hed or platen d,

an indispensible feature in a stamp for general oiiccA use; but'I prefer to make the plate and guides separate from the neck or hanger l). .l

rlhe rear-side of the platef is provided with a dovetail recess, indicated by the dotted lines t, fig. l, and

the headlot the hanger D made to fit, as shown in` 'proper dating and hour-type, if desired, constitutes the most perfect and convenient post-office stamp yet invented, because it is self-inking, while the ordinary hand-stamp requires a separate movement to ink the type.

rlhe pressure upon the plate f in stamping 'Ihc plate j, foi'ining the connection between'the guides a.. and the hanger D is recessed upon the lower side, to receive the pad g, figs. 2 and 3, which coiiveys and distributes the ink from the `fountain h to the die-plate A, and this recess is made re-entrai'it at t-lie sides or ends, as shown in fig. 6, to prevent the pad from dropping out,.and, at the same time, permit its removal forcleaning or renewal..

The ink flows f'i'oni the fountain h to the pad through:

a small opening, i', fig.3, and the fibrous character ot the pad quickly distributes it over the whole surface. To regulate and cut off' this flow, I provide the plug Z, which is iitted'iiito a suitable seat or socket in the plate f, between the fountain and the pad.

This plug has a vgroove or recess, '0, upon one o`r both sides, which is proportionedto contain ink enough to lill the porcs of the pad, and an aperture in the bottom of the fountain communicates with the recess when the plug is turned to the proper point.

It plain that, when a recess, o, is filled with ink, it is allowed to ilow through the opening fi to the pad by simply reversing the plug, while communication with the fountain is simultaneously cut oi` by the solid portions'of the plug. By providing two recaisses, o, at opposite points upon the latter, onev may befilling while the other is emptying.

In a dating-stamp it is necessary that provision be made for changing' the portion of' the die. indicating the Vdate. For this `purpose apertures are formed through thedie-plate, the sides of which are inclined so as to receive the dovetailed dating-types a, figs. 2

and 3.

These loose types aiexhimped in position by a plate, in, which is secured to the back of the diepiate by sliding it ina dovetailed recess, as shown iii gs.l and 3, or by means oi"A suitable 'thumb-screws,

Thus, when the die-plate is partly or wholly rcversed, shown in dotted lines in iig. 2,l the plate m ima-y be readily slipped out, and the loose types removed and,replaeed by others.

'lo assist in making such changes, the die-plate may be clamped at any point of its vertical adjustment by means of the clamp-screw, fr, inthe yoke B.

The horizontal bar of the yoke B is fitted to move said bar concentric with the tube'h, upon or into vwhich the ferrule of the handle Gis screwed.

The -haudle G is composed ofthe outer" portion s,

g. 2, of ornamental wood or other suitable material, and the metallic tube t, which contains the reaction spring fr. This spring rests upon the upper extremity ot' the reservoir h, and, since the latter is securely attached to the hanger D, it follows that the spring returns the handle, yoke, and die-plate, to their original position, after the required impression has beer` made.

'lhe ink-reservor is closed by a stopper, k, and it is obviously necessary to remove t-he handle to obtain access to the former for refilling, which is done by unscrewing it from the boss upon the yoke, thus leaving the upper portion of the reservoir exposed. v

It will he seen that,` unless 'prevented' by some means, the spring lr would be liable tol drop outof the tube' t when the latter -is removed, and cause considerable trouble in replacing it.

`To obviate this diticulty, I provide the disk a', gs.

2 and 5, resting upon a slight ledge or ange formed upon the inner periphery of the tube t, which lv'etains the spring within the latter, while, at the same time, the handle is free to pass down over the reservoir h and compress the spring.

yThis: disk is convenientlyintroduced through notches upon opposite sides of the flange, as indicated in iig. 5. The tube t strengthens the handle and cheapens lits construction, and its lower end forms the ferrule, by which itis attached to the yoke B. 4

The upper extremity of the4 spring 1' may hear against the handle directly, or against the solid end of the tube.

What 1 claim as my invention is- 1. The detachable stamping apparatus, when provided with a reversible self-inking die-plate, in comhination with the bed orxplatf'orm E, substantially in the manner shown, and for the purposes described.

2. In combination with the reservoir h and distrihuting-pad g, theink-gauge l, constructed and arranged to operate substantially in .the manner and for the purposes set forth.
